Hey I'm new to pontiacs and just finished installing my 400 motor and am now working on getting a new carb. In my process i disconnected the 3 lines to my heater control valve and cannot for the life of me remember what lines go to what nipples on the valve. my valve has 5 nipples 3, 2 of which are blocked by a rubber block. the three nipples are labled CA,MT, and DA. Can anyone please help me in telling me what goes to where. Any help is much appreciated.
